摘要
基于二自由度线性车辆模型,研究轮胎侧偏刚度、横摆角速度波动固有频率(f_(0))对车辆操纵性能的影响,计算车辆对前轮转角阶跃输入时瞬态响应的客观评价指标,并利用线性回归方法分析轮胎侧偏刚度和f_(0)与实车主观性能评价结果的相关性。结果表明,与侧偏刚度相比,f_(0)与实车转向响应评分具有更强的正相关性。
Based on a two-degree-of-freedom linear vehicle model,the influence of the cornering stiffness and yaw velocity fluctuation natural frequency(f_(0))on vehicle handling performance was studied.Objective evaluation parameters for the transient response of the vehicle to the front-wheel steering angle step input were calculated,and a linear regression method was used to analyze the correlation between cornering stiffness and f_(0) with subjective evaluation score of vehicle performance.The results showed that,compared with the cornering stiffness,f_(0) had a stronger positive correlation with the vehicle steering response score.
